Detecting and predicting spatial and interannual patterns of temperate forest springtime phenology in the eastern U.S. [PDF]

open access: yes, 2002
We performed a diagnostic analysis of AVHRR-NDVI and gridded, temperature data for the deciduous forests of the eastern U.S., calibrating temperature accumulation model with satellite data for 1982–1993.

Soil Management Effects on Grapevine Water Uptake Depth in a Mediterranean Vineyard

open access: yesEuropean Journal of Soil Science, Volume 77, Issue 2, March–April 2026.
Stable isotope evidence of vine water uptake depth under spontaneous cover crop and tillage. ABSTRACT In Mediterranean vineyards, soils are often managed with tillage or herbicides to limit weed growth and competition for resources. However, with rising concerns about water scarcity and climate change, cover crops are being reconsidered as sustainable ...

Where is the optimum? Predicting the variation of selection along climatic gradients and the adaptive value of plasticity. A case study on tree phenology

open access: yesEvolution Letters, 2020
Many theoretical models predict when genetic evolution and phenotypic plasticity allow adaptation to changing environmental conditions. These models generally assume stabilizing selection around some optimal phenotype. We however often ignore how optimal

Shifting body weight-fecundity relationship in a capital breeder : maternal effects on egg numbers of the autumnal moth under field conditions [PDF]

open access: yes, 2013
In the literature, various environmental factors are described as being capable of influencing the reproductive output of insect females irrespective of their body size. Still, female body size or weight is widely used as a proxy for fecundity.

Comprehensive ecosystem model-data synthesis using multiple data sets at two temperate forest free-air CO2 enrichment experiments: Model performance at ambient CO2 concentration [PDF]

open access: yes, 2014
Free-air CO2 enrichment (FACE) experiments provide a remarkable wealth of data which can be used to evaluate and improve terrestrial ecosystem models (TEMs).

Rethinking False Spring Risk [PDF]

open access: yes
Temperate plants are at risk of being exposed to late spring freezes. These freeze events - often called false springs - are one of the strongest factors determining temperate plants species range limits and can impose high ecological and economic damage.

What role for photoperiod in the bud burst phenology of European beech [PDF]

open access: yes, 2018
A considerable number of studies have investigated the phenology of European beech using models, experimental controlled conditions, or descriptive surveys of patterns in situ.

Why would plant species become extinct locally if growing conditions improve? [PDF]

open access: yes, 2012
wo assumptions underlie current models of the geographical ranges of perennial plant species: 1. current ranges are in equilibrium with the prevailing climate, and 2.

Genetic variation and heritability estimates of Ulmus minor and Ulmus pumila hybrids for budburst, growth and tolerance to Ophiostoma novo-ulmi

open access: yesiForest - Biogeosciences and Forestry, 2015
Seedlings obtained by crossing Ulmus minor and U. minor × U. pumila clones were assessed for flowering, bark beetle damage, vegetative budburst, height growth and resistance to Ophiostoma novo-ulmi.
